Check Digit Verification of cas no

The CAS Registry Mumber 4942-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4942-77:
(6*4)+(5*9)+(4*4)+(3*2)+(2*7)+(1*7)=112
112 % 10 = 2
So 4942-77-2 is a valid CAS Registry Number.

KMnO4-mediated oxidative C[sbnd]N bond cleavage of tertiary amines: Synthesis of amides and sulfonamides

Zhang, Zhang,Liu, Yong-Hong,Zhang, Xi,Wang, Xi-Cun

, p. 2763 - 2770 (2019/04/10)

KMnO4-mediated oxidative C[sbnd]N bond cleavage of tertiary amines producing secondary amine was introduced, which was trapped by electrophiles (acyl chloride and sulfonyl chloride) to form amides and sulfonamides. The reaction could take place at mild condition, tolerating a wide range of function groups and affording products in moderate to excellent yields.
